Historical use of pesticides and rapid urbanization have left their mark on the chemistry of bottom sediments in Lorence Creek Lake (fig. 1) in the northern part of San Antonio, Tex. Several metals, organochlorine compounds (pesticides and polychlorinated biphenyls [PCBs]), and polycyclic aromatic hydrocarbons (PAHs) detected in bottom sediments of the lake have temporal trends indicating anthropogenic (human) sources. Lorence Creek Lake is not unique; the same metals and organic compounds are routinely found in lake sediments in urbanizing watersheds (Van Metre and Callender, in press).
